mikromedia 7 CAPACITIVE FPI is a compact developmentboard, designed as a complete solution for the rapiddevelopment of multimedia and GUI-centric applications.Featuring a large 7” capacitive touch screen driven by apowerful graphics controller that can display a true-color24-bit color palette (16.7 million colors), DSP-poweredembedded sound CODEC IC, MCU Card socket, a set offive compact mikroBUS Shuttle connectors, a set of veryuseful general-purpose sensors and devices, and more, itrepresents a perfect solution for the rapid development ofmany different types of applications.(on the MCU Card that supports it) and two 1x26 pin headers.However, five compact-sized mikroBUS Shuttle connectorsrepresent the most distinctive connectivity feature, allowingaccess to a huge base of Click boards , growing on a dailybasis.At its core, there is an MCU Card socket which allowsmikromedia 7 CAPACITIVE FPI (referred to as “mikromedia 7”in the following text) to use different microcontrollers (MCUs)mounted on a standardized MCU Card, regardless of theirvendor or architecture. Although MCU Card standard enablesyou to place any MCU Card available, to fully use all mikromedia7 onboard features, MCUs whose pin count is 144 or more arethe right choice. This provides a tremendous amount of flexibility,allowing mikromedia 7 to adapt to any specific applicationrequirements, be it a demanding task of displaying fluid andglitch-free multimedia content, or something much simpler.The mikromedia 7 development board features manyconnectivity options, including USB, Ethernet, RF, WiFi, CANThe usability of mikromedia 7 doesn’t end with its ability toaccelerate the prototyping and application developmentstages: it is designed as a complete solution which can beimplemented directly into any project, with no additionalhardware modifications required. We offer two types ofmikromedia 7 FPI boards. The first one has a TFT display witha bezel around it and is ideal for handheld devices. The othermikromedia 7 FPI board has a TFT display with a metal frame,and four corner mounting holes that enable simple installationin various kinds of industrial appliances. With both types, anice casing is all that you need to turn the mikromedia 7 FPIdevelopment board into a fully functional design.Each section of mikromedia 7 is clearly marked, offering anintuitive and clean interface. Each section contains a singlefeature (WiFi, RF, MP3 ) along with the accompanyingcomponents and configuration jumpers. This makes workingwith the development board much simpler and thus, faster.

Likewise, the mikromedia 7 developmentboard is equipped with a pair of complementary connectors(3), eliminating any possibility of the incorrect orientation,allowing MCU Card to be installed very easily.Besides these two 168-pin mezzanine connectors, MCU CardPAGE 6may also contain multiplexing circuits, Ethernet PHY ICs,CAN transceivers and connectors, crystal oscillators, clockgenerators, and other electronic components necessaryfor the proper operation of the MCU. This makes each MCUCard a self-contained unit, allowing the development boardto operate on a logic level, not having to facilitate specificrequirements of many different MCUs.MCU Card must be installed prior to using the mikromedia 7development board.

5Figure 2: Front and back partial view1.1 MCU programming/debuggingThe installed MCU (referred to as “host MCU” in the following text) can beprogrammed and debugged over the JTAG/SWD compatible 2x5 pin header (1),labeled as PROG/DEBUG. This header allows an external programmer (e.g.CODEGRIP or mikroProg) to be used. To enable the JTAG interface, two SMDjumpers labeled as JP6 and JP8 (2), located in the PROG/DEBUG section, haveto be populated. These jumpers are unpopulated by default, optimizing the pincount so that more pins could be used for a large number of onboard modulesand peripherals. Hence, SWD interface is enabled/supported out of the box.If your MCU card has preprogrammed bootloader, MCU can be programmed byusing the mikrobootloader application. All the information about the bootloadersoftware can be found on the following page: www.mikroe.com/mikrobootloaderA switch labeled as SW1 (3) is used to specify whether CODEGRIP/mikroProg ora third-party programmer is connected to the JTAG/SWD header.SW1 – left position: to use CODEGRIP/mikroProgSW1 – right position: to use a third-party programmer1.2 MCU resetThe mikromedia 7 development board is equipped with the reset button labeled asRST (4), located on the back of the board. It is used to generate a LOW logic levelon the MCU reset pin. The RST pin of the host MCU is also routed to the pin 1 of the241 2mikromedia 7 CAPACITIVE FPI U S E R M A N U A L1x26 pin header (5), allowing an external signal to reset the device.NOTEPAGE 9Before usage, please check if the programmer pinout and the 2x5 pin headerpinout are compatible. Based on the used programmer/debugger toolpinout, a coresponding addapter might be needed (e.g. mikroProg for PIC).

2. Power supply unitThe power supply unit (PSU) (1) provides clean and regulatedpower, necessary for proper operation of the mikromedia 7development board. The host MCU, along with the rest ofthe peripherals, demands regulated and noise-free powersupply. Therefore, PSU is carefully designed to regulate,filter, and distribute the power to all parts of mikromedia 7.It is equipped with four different power supply inputs,offering all the flexibility that mikromedia 7 needs, especiallywhen used on the field or as an integrated element of alarger system. In the case when multiple power sources areused, an automatic power switching circuit with predefinedP A G E 12priorities ensures that the most appropriate will be used.The PSU also contains a reliable and safe battery charging circuit,which allows a single-cell Li-Po/Li-Ion battery to be charged.Power OR-ing option is also supported providing uninterruptedpower supply (UPS) functionality when an external or USB powersource is used in combination with the battery.1Figure 3: Power supply unit PI U S E R M A N U A L

2.1 Detailed descriptionHyperSpeed Control and HyperLight Load architectures, providing anultra-fast transient response and high light-load efficiency. Each of thetwo buck regulators is used to supply power to the corresponding powersupply rail (3.3V and 5V), throughout the entire development board and2.2 Voltage referenceAt the input stage of the PSU, the MIC2253, a high-efficiency boostregulator IC with overvoltage protection ensures that the voltage input atthe next stage is well-regulated and stable. It is used to boost the voltageof low-voltage power sources (a Li-Po/Li-Ion battery and USB), allowingthe next stage to deliver well-regulated 3.3V and 5V to the developmentboard. A set of discrete components are used to determine if the inputpower source requires a voltage boost. When multiple power sources areconnected at once, this circuitry is also used to determine the input prioritylevel: externally connected 12V PSU, power over USB, and the Li-Po/Li-Ionbattery. The transition between available power sources is designed toprovide uninterrupted operation of the development board.The MCP1501, a high-precision buffered voltage reference from Microchipis used to provide a very precise voltage reference with no voltage drift. Itcan be used for various purposes: the most common uses include voltagereferences for A/D converters, D/A converters, and comparator peripheralson the host MCU. The MCP1501 can provide up to 20mA, limiting its useexclusively to voltage comparator applications with high input impedance.Depending on the specific application, either 3.3V from the power rail,or 2.048V from the MCP1501 can be selected. An onboard SMD jumperlabeled as REF SEL, located in a separate section labeled as VREF, offerstwo voltage reference choices:The next PSU stage uses two MIC28511, synchronous step-down (buck)regulators, capable of providing up to 3A. The MIC28511 IC utilizes the REF: 2.048V from the high-precision voltage reference IC 3V3: 3.3V from the main power supply railmikromedia 7 CAPACITIVE FPI U S E R M A N U A LPOWE R S U P P LYconnected peripherals.P A G E 13The PSU has a very demanding task of providing power for the host MCUand all the peripherals onboard, as well as for the externally connectedperipherals. One of the key requirements is to provide enough current,avoiding the voltage drop at the output. Also, the PSU must be able tosupport multiple power sources with different nominal voltages, allowingswitching between them by priority. The PSU design, based on a set ofhigh-performance power switching ICs produced by Microchip, ensures avery good quality of the output voltage, high current rating, and reducedelectromagnetic radiation.

2.3 PSU connectorsAs explained, the advanced design of the PSU allows several types of powersources to be used, offering unprecedented flexibility: when poweredby a Li-Po/Li-Ion battery, it offers an ultimate degree of autonomy. Forsituations where the power is an issue, it can be powered by an external12VDC power supply, connected over the 5.5mm barrel connector or overthe two-pole screw terminal. Power is not an issue even if it is poweredFigure 4: Power supply connectors viewover the USB cable. It can be powered over the USB-C connector, usingpower supply delivered by the USB HOST (i.e. personal computer), USB walladapter, or a battery power bank.There are four power supply connectors available, each with its uniquepurpose: CN9: USB-C connector (1) CN11: 12VDC barrel-type connector (2) TB1: Screw terminal for an external 12VDC PSU (3) CN12: Standard 2.5mm pitch XH battery connector (4)2.3.1 USB-C connectorThe USB-C connector (labeled as CN9) provides power from the USB host(typically PC), USB power bank, or USB wall adapter.

The charging processis indicated by BATT indicator, located on the back of mikromedia 7.Figure 7: Battery power supply tableThe PSU module also includes the battery charger circuit. Depending on theoperational status of the mikromedia 7 development board, the chargingcurrent can be either set to 100mA or 500mA. When the developmentboard is powered OFF, the charger IC will allocate all available power for thebattery charging purpose. This results in faster charging, with the chargingP A G E 16current set to approximately 500mA. While powered ON, the availablecharging current will be set to approximately 100 mA, reducing the overallpower consumption to a reasonable level.NOTEUsing low-quality USB hubs, and too long or low-quality USB cables,may cause a significant USB voltage drop, which can obstruct thebattery charging process.mikromedia 7 CAPACITIVE FPI U S E R M A N U A L

2.4 Power redundancy anduninterrupted power supply (UPS)The PSU module supports power supply redundancy: it will automaticallyswitch to the most appropriate power source if one of the power sourcesfails or becomes disconnected. The power supply redundancy also allowsfor an uninterrupted operation (i.e. UPS functionality, the battery will stillprovide power if the USB cable is removed, without resetting mikromedia 7during the transition period).P A G E 172.5 Powering upthe mikromedia 7 boardAfter a valid power supply source is connected (1), mikromedia 7 can bepowered ON. This can be done by a small switch at the edge of the board,labeled as SW2 (2). By switching it ON, the PSU module will be enabled, and12the power will be distributed throughout the board. A LED indicator labeledas PWR indicates that the mikromedia 7 is powered ON.mikromedia 7 CAPACITIVE FPI U S E R M A N U A LFigure 8: Battery power supply connection view

Data storageP A G E 20DATA STO RAGEThe mikromedia 7 development board is equipped with twotypes of external memory: with a microSD card slot, and with1a Flash memory module.4.1 microSD card slot4.2 External flash storageThe microSD card slot (1) allows storing large amounts of data externally,on a microSD memory card. It uses the Serial Peripheral Interface (SPI) forcommunication with the MCU. The microSD card detection circuit is alsoprovided on the board. The microSD card is the smallest SD Card version,measuring only 5 x 11 mm. Despite its small size, it allows tremendousamounts of data to be stored on it. In order to read and write to the SDCard, a proper software/firmware running on the host MCU is required.mikromedia 7 is equipped with the SST26VF064B Flash module (2). TheFlash memory module has a density of 64 Mbits. Its storage cells arearranged in 8-bit words, resulting in 8Mb of non-volatile memory in total,available for various applications. The most distinctive features of theSST26VF064B Flash module are its high speed, very high endurance, andvery good data retention period. It can withstand up to 100,000 cycles, andit can preserve the stored information for more than 100 years.

5.1 EthernetP A G E 23Some MCUs feature an integrated Ethernet peripheral module, whichcontains the entire communication stack on the chip. MCU Cards equippedwith such MCUs, are already provided with the Ethernet physical layertransceiver IC (PHY IC). This allows the Ethernet circuit of the mikromedia7 development board to be reduced only to isolation transformers/chokes,a pack of TVS diodes for electrostatic discharge (ESD) protection, and anRJ-45 connector (1), allowing the development board to be safely andreliably connected to the Ethernet network.CO N N E CT IVIT YEthernet is a popular computer networking technology for local areanetworks (LAN). Systems communicating over Ethernet divide a stream ofdata into individual packets, known as frames. Each frame contains sourceand destination addresses and error-checking data so that damaged datacan be detected and re-transmitted. This makes the Ethernet protocol verypopular for communication over longer distances or in noisy environments.Figure 12: RJ-45 connector view1mikromedia 7 CAPACITIVE FPI U S E R M A N U A L

5.2 WiFiA very popular WiFi module (1) labeled as CC3100 allows WiFi connectivity.This module is the complete WiFi solution on a chip: it is a powerful WiFinetwork processor with the power management subsystem, offering theTCP/IP stack, powerful crypto engine with 256-bit AES support, WPA2security, SmartConfig technology, and much more.By offloading the WiFi and Internet handling tasks from the MCU, it allowsthe host MCU to process more demanding graphical applications, thusCO N N E CT IVIT Ymaking it an ideal solution for adding WiFi connectivity to mikromedia 7.It uses the SPI interface to communicate with the host MCU, along withseveral additional GPIO pins used for the reset, hibernation, and for theinterrupt reporting.An SMD jumper labeled as FORCE AP (2) is used to force the CC3100module into an Access Point (AP) mode, or into a Station mode. However,the operating mode of the CC3100 module can be overridden by theP A G E 24software. This SMD jumper offers two choices:0: the FORCE AP pin is pulled to a LOW logic level, forcing the CC3100module into the STATION mode1: the FORCE AP pin is pulled to a HIGH logic level, forcing the CC3100module into the AP modeThere is a chip antenna (3) integrated on the PCB of the mikromedia 7, aswell as SMA connector for external WiFi antenna.321Figure 13: RF and WiFi sections PI U S E R M A N U A L

5.3 RFmikromedia 7 offers communication over the world-wide ISM radiofrequency (RF) band. The ISM band covers a frequency range between2.4GHz and 2.4835GHz. This RF band is reserved for industrial, scientific,and medical use (hence the ISM abbreviation). In addition, it is globallyavailable, making it a perfect alternative to WiFi, when the M2Mcommunication over a short distance is required.mikromedia 7 uses the nRF24L01 (4), a single-chip 2.4GHz transceiverSemiconductors. It is a perfect solution for ultra-low power wirelessapplications. This transceiver relies on the GFSK modulation, allowing datarates in the range from 250 kbps, up to 2 Mbps. The GFSK modulationis the most efficient RF signal modulation scheme, reducing the requiredbandwidth, thus being more efficient. The nRF24L01 also features theproprietary Enhanced ShockBurst , a packet-based data link layer.Besides other functionalities, it offers a 6-channel MultiCeiver feature,CO N N E CT IVIT Ywith an embedded baseband protocol engine, produced by Nordicwhich allows using the nRF24L01 in a star network topology. TheBesides the SPI lines, it uses additional GPIO pins for the SPI Chip Select,Chip Enable, and for the interrupt. The RF section of the mikromedia 7 alsofeatures a small chip antenna (5), as well as SMA connector for externalantenna.45mikromedia 7 CAPACITIVE FPI U S E R M A N U A LP A G E 25nRF24L01 uses the SPI interface to communicate with the host MCU.

PCORONGRAMMINN E CT IVIT YG5.4 USBThe host MCU is equipped with the USB peripheral module, allowingsimple USB connectivity. USB (Universal Serial Bus) is a very popularindustry standard that defines cables, connectors, and protocols used forcommunication and power supply between computers and other devices.Mikromedia 7 supports USB as HOST and USB as DEVICE, allowing thedevelopment of a wide range of various USB-based applications. It isequipped with the USB-C connector (1), which offers many advantages,23Figure 14: USB and 1x26 pin header view1P A G E 26compared to earlier types of USB connectors (symmetrical design, highercurrent rating, compact size, etc).The USB mode selection is done using a monolithic controller IC. This ICprovides Configuration Channel (CC) detection and indication functions.To set up mikromedia 7 as a USB HOST, the USB PSW pin should be setThe USB ID pin is used to detect the type of the device attached to the USBport, according to the USB OTG specifications: the USB ID pin connected toGND indicates a HOST device, while the USB ID pin set to a high impedancestate (HI-Z) indicates that the connected peripheral is a DEVICE.to a LOW logic level (0) by the host MCU. If set to a HIGH logic level (1),mikromedia 7 acts as a DEVICE. While in HOST mode, mikromedia 7provides power over the USB-C connector. The USB PSW pin is driven bythe host MCU, allowing the software to control the USB mode.When mikromedia 7 is working in USB HOST mode, it must not bemounted to another USB HOST (such as PC).mikromedia 7 CAPACITIVE FPI U S E R M A N U A LNOTE

5.5 CAN5.6 1x26 pin headersAlthough not included on the mikromedia 7 development board, CAN busMost of the host MCU pins are routed to two 1x26 pin headers (2), makingconnectivity can be added as a bonus feature, if the MCU on the installedthem available for further connectivity. In addition to MCU pins, someMCU Card supports it. Similarly to Ethernet, components related to the CANadditional peripheral pins are also routed to this header.
